Yes, the short and sweet interaction is right out of DR too... MWD says the exact same thing... so consider it doubly good advice.
Two or three years to ride out the affair is quite exhausting I can imagine.. been there myself...
Most people dont have the strength or the patience to deal... In your favour is knowing the OW really doen'st want your H long term, so you don't feel threatened in teh long term.. its only the short term that's a nightmare. Many of the others here are facing a potential long term threat, so they cant' afford to wait and ride it out like this... To be honest you are at an advantage comparative to others here... especially the fact that you have three years in already... Those two have likley squeezed all the fun out of this affair by now...
